What is the best way to distribute multiple entries across multiple pages in a PHP guestbook?

When dealing with multiple entries in a PHP guestbook, it is best to distribute them across multiple pages to improve the user experience and prevent long loading times. One way to achieve this is by implementing pagination, where a certain number of entries are displayed on each page. This can be accomplished by using PHP to query the database for the total number of entries, calculating the total number of pages needed based on a set number of entries per page, and then using SQL LIMIT and OFFSET clauses to fetch the correct entries for each page. 

<?php
// Establish a database connection
$connection = new mysqli('localhost', 'username', 'password', 'database');

// Set the number of entries per page
$entriesPerPage = 10;

// Get the total number of entries
$totalEntries = $connection->query("SELECT COUNT(*) FROM guestbook")->fetch_row()[0];

// Calculate the total number of pages
$totalPages = ceil($totalEntries / $entriesPerPage);

// Get the current page number from the URL
$page = isset($_GET['page']) ? $_GET['page'] : 1;

// Calculate the offset for the SQL query
$offset = ($page - 1) * $entriesPerPage;

// Fetch entries for the current page
$result = $connection->query("SELECT * FROM guestbook LIMIT $entriesPerPage OFFSET $offset");

// Display entries
while($row = $result->fetch_assoc()) {
    echo $row['name'] . ': ' . $row['message'] . '<br>';
}

// Display pagination links
for($i = 1; $i <= $totalPages; $i++) {
    echo '<a href="?page=' . $i . '">' . $i . '</a> ';
}

// Close the database connection
$connection->close();
?>
